Short term bacterial community structure dynamics in forest soil and litter: an in situ study in a CarboEurope site.

International audience; Acting as both sink and source in the terrestrial carbon cycle, soils play an important role. In forests, soils contain up to 70% of total ecosystem C and contribute to 40% to 70% of total ecosystem respiration. Therefore, in a climate change context, understanding soil microbial community dynamics and its consequences on soil functioning is a major issue. The objective of this study was to determine if changes in the inputs of fresh litter quantity could influence the structure of bacterial communities (named BCS) and their dynamics in a forest soil. The experiment took place in Barbeau national forest (CARBOEUROPE site; Fontainebleau, France). Three treatments of f…
